Anaerobic digestion, renewable energy guide
What is anaerobic digestion?
Anaerobic digestion is the process in which organic materials such as food or animal waste are broken down by microorganisms, in an ananerobic (oxygen free) environment – the digestor. This process produces biogas for combustion in a Combined Heat and Power (CHP) unit or boiler or can be enriched with propane to produce biomethane. As a by-product of digestion, digestate is also produced which is a natural biofertilizer and can be spread back onto the land as it is rich in nutrients.
